Answer:
x=1.25, y=1.75
Step-by-step explanation:
The two triangles formed (one triangle with side lengths of 5, 7, 8 and another with sides 5+x, 10, and 7+y) are similar, because they share the same angle measures.
Now, 2 sides given that we can compare ratios with are the side with length 8, and the side with length 10. 10/8= 1.25, which is the ratio of the sides on these 2 triangles.
Now we want to find what the side '5+x' is equal to. To do that we can use our ratio, and multiply 5 by 1.25 to find '5+x'. This is 6.25. To find x, all we need to do is subtract 5 from 6.25, which is 1.25.
Let's find y now. Do the same thing that we did with the side '5+x'; find what '7+y' is by multiplying 7 by 1.25, which is 8.75. 8.75-7= 1.75.
Hope this helps! :)

Answer:
b and d I think are both right but if you can only pick one go with B
The measure that could be the side lengths of a right triangle is 30 cm, 72 cm, 78 cm, the correct option is B.
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.
We are given that;
The right triangle
Now,
We can use this equation to test each option by plugging in the values and checking if they satisfy the equation.
A. 7 cm, 21 cm, 25 cm
7^2 + 21^2 = 25^2
49 + 441 = 625
490 = 625
False
This option does not satisfy the Pythagorean theorem, so it cannot be the side lengths of a right triangle.
B. 30 cm, 72 cm, 78 cm
30^2 + 72^2 = 78^2
900 + 5184 = 6084
6084 = 6084
True
Therefore, by right angle triangle the answer will be 30 cm, 72 cm, 78 cm.

Answers
Answer:
not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)
Answer:
x= 5, y= 3/2
Step-by-step explanation:
5x -4y =19 (Equation 1)
x+ 2y=18 (Equation 2)
Using substitution method,
From equation(2),make x the subject of formula
x= 8-2y (Equation 3)
Substitute equation 3 into equation 1
5x -4y= 19
5(8-2y) -4y = 19
40 -10y -4y = 19
40-14y=19
Collect like terms
40-19=14y
21=14y
y= 21/14 = 3/2
Substitute for y in equation 3
x= 8 -2y
8- 2(3/2)
=8 -3
x = 5

James and Willis are both painting a room. James could complete it in 6 hours by himself. Together they can complete the room in 2 hours. How long would it take Willis to paint the room by himself?
Answers
Answer: Willis will take 3 hours to paint the room by himself.
Step-by-step explanation:
Given: Time taken by James to complete job by himself = 6 hours
Let Time taken by Willis to complete job by himself = t hours
Together they take 2 hours.
[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]
So, Willis will take 3 hours to paint the room by himself.

there are 8 elements in a set a, there are 5 elements in a set b, and 3 elements of those are shared both a and b. how many elements are in union of a and b?
Answers
There are 10 elements in the union of A and B.
What is the union of A and B?
The union of A and B will contain all of the elements found in either A or B or both sets. The union of sets is represented by the set notation. To find the union of two sets A and B, use the union B formula. Simply putting all of A and B's elements in one set and removing duplicates yields the union.So, set A has 8 elements and set B has 5 elements.
Both have 3 elements in common. So, 3 + (8 - 3) + (5 - 3) = 3 + 5 + 2 = 10Therefore, there are 10 elements in the union of A and B.

two negative integers are 8 units apart on the number line and have a product of 308. which equation could be used to determine x, the smaller negative integer? x2 8x – 308
Answers
The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).
As per the question, the small integer is x. So, the large integer will be (x + 8).
Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -
x (x + 8) = 308
Performing multiplication on Left Hand Side of the equation
x² + 8x = 308
Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -
x² + 8x – 308 = 0
On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.
x² + 8x – 308 = 0
x² + 22x - 14x – 308 = 0
x (x + 22) - 14 (x + 22) = 0
(x + 22) (x - 14) = 0
x = -22 and 14
Since the numbers are negative, hence, value of small number is -22.
Large number = -22 + 8
Large number = -14
Thus, the small and large number is -22 and -14.
Therefore, the correct equation is x² + 8x – 308 = 0.
